A Parallel time-domain Maxwell solver using upwind schemes and triangular meshes
Résumé
A finite-volume/finite-element method developped in CFD is applied to solve numerically the time-dependent 2D Maxwell system. We use a third-order accurate explicit scheme with triangular meshes. We are particularly concerned here with scattering problems for both homogeneous and non-homogeneous materials. Radar cross section calculations are presented and compared with exact or integral method solutions. A parallel version of the algorithm on the connection machine is presented and the performances are compared with those obtained with a fully vectorized version on the Cray YMP.
